Detailed Description

WorldCanvas event-based polygon region drawer.

Intended use:

Public interface

Review Status

<prerequisites> WCRectTool </prerequisites>

Etymology

WCPTRegion stands for WorldCanvas Polygon Tool Region

Synopsis

This class finalises the functionality in WCRectTool to implement event-based drawing of polygonal regions on a WorldCanvas. casacore::Double clicking inside the constructed polygon emits the region, whilst pressing Escape cancels the region.

Example

Motivation

Polygonal regions are the most common regions, and constructing them visually can be very efficient.

Handle double-click inside the polygon.

Invokes regionReady().

Reimplemented from casa::MWCPolyTool.

void casa::MWCPTRegion::getLinearCoords	(	casacore::Vector< casacore::Double > &	x,
		casacore::Vector< casacore::Double > &	y
	)

protected

get the linear coords of the current ploygon region

void casa::MWCPTRegion::getWorldCoords	(	casacore::Vector< casacore::Double > &	x,
		casacore::Vector< casacore::Double > &	y
	)

protected

get the world coords of the current polygon region

virtual void casa::MWCPTRegion::regionReady ( )

inlineprotectedvirtual

This function is called when a region is deliberately "finished" by the user.

It can be implemented to do further actions, such as report the region to the application.

Reimplemented in casa::QtOldPTRegion.
